If these are the little craps in the swarms, then I am here to say that they don’t have a first person hit box. Go into third person with a pike or spear and just start stabbing them. So easy once you know this.
For some reason on single player when I was targeted by them i didnt have a torch becuase i was building my base they chased me like 5 minutes i think and then died i saw them on my base floor dead. So if you dont have a torch stay away and survive
